Find the least 5-digit odd number that can be formed from the digits1 2 0 3 8

According to the general equation for conditional probability if p(anb)=3/7 and p(b)=7/8 what is p(a i b)

M? aoc=96 ? space, m, angle, a, o, c, equals, 96, degree \qquad m \angle boc = 8x - 67^\circm? boc=8x? 67 ? space, m, angle, b, o, c, equals, 8, x, minus, 67, degree \qquad m \angle aob = 9x - 75^\circm? aob=9x? 75 ? space, m, angle, a, o, b, equals, 9, x, minus, 75, degree find m\angle bocm? bocm, angle, b, o, c:

Ineed the answers for this one as well!
